Answer 1

The Meade ETX 125 already has an extremely long focal length of 1900 mm. I wouldn't recommend using _any_ Barlow when the focal length is already so long. An unBarlowed 9 mm eyepiece will give you about as much magnification as the telescope can handle, aroun 211x. Don't believe Meade's claims of higher magnifications, 200x to 250x is the real world maximum magnification for a 5" scope.

Answer 2

The Meade 126 is a short barlow designed to work in telescopes with limited focus range. The series 5000 TeleXtenders are more complex (and expensive) "power multipliers" using a 4-element design. The advantages over conventional barlows supposedly include a flatter field and less vignetting of longer FL eyepieces. In 1.25" it comes in three magnifications - 2x, 3x, and 5x. The number indicates how much your eyepiece magnification is increased. If you have an eyepiece that gives you 50 power, the 2x TeleXtender will give you 100 power, and the 3x 150.
